I got a quick and probably dumb question. Anyways I'm looking for new exhaust pipe. The magnaflow exhaust pipe for the 5.7l(whatI have) is 4in and my muffler will onlyfit a 2.75 to 3 in. pipe. Well the pipe for the 4.7 is 3in. I was wondering if that would fit my truck or if I'm going to have to look some more.

well if its a 4in pipe i dont think it will fit a 4in muffler outlet...howd you get all different sizes? did you check the outlet size?
